Contact the clerk of court, and explain everything to them. If they do give you a new court date make sure you get something in writing to verify the new court date.

This same thing happened to me in Gilbert. Just go to the assigned court date and they will give you an additional eight weeks. Contacting the court will get you nowhere but the court hearing is extremely informal and brief. As far as what to say, just say that you want to go to traffic school. There will be a dozen or so other people doing the same thing.
You should show up to Court and explain what happened. If the Court is understanding, you are more likely than not to get the continuance. You may also need to have the prosecuting attorney on your side about things as well.
